PSC 134.14 PSC 134.14 Adjustment of bills.

PSC 134.14(1) (1) Whenever a meter is found to have a weighted average error of more than 2% fast as tested in the manner specified in s. PSC 134.28, a recalculation of bills for service shall be made for the period of inaccuracy assuming an inaccuracy equal to the weighted average error. Weighted average error refers to 80% of the open rate plus 20% of the check rate. The recalculation shall be made on the basis that the service meter should be 100% accurate.

PSC 134.14(2) (2) If the period of inaccuracy cannot be determined, it shall be assumed that the full amount of inaccuracy existed during the last half of the period since the previous test was made on the meter; however, the period of accuracy shall not exceed one-half the required test period.

PSC 134.14 Note Note: If the meter test period is 15 years and the meter had been in service for 16 years, the period of accuracy shall be 7½ years, and the period of inaccuracy shall be 8½ years.

PSC 134.14(3) (3) If the average gas bill of a customer does not exceed $10 per month over the refund period the monthly consumption of which the refund is calculated may be averaged.

PSC 134.14(4) (4) If the recalculated bills indicate that more than $1 is due an existing customer or $2 is due a person no longer a customer of the utility, the full amount of the calculated difference between the amount paid and the recalculated amount shall be refunded to the customer. The refund to an existing customer shall be a credit to the customer’s current bill. If the amount of the credit is greater than the current bill, the amount in excess of the current bill shall, at the discretion of the customer, be made in cash or as credit on future bills. If a refund is due a person no longer a customer of the utility, a notice shall be mailed to the last known address, and the utility shall upon request made within 3 months thereafter refund the amount due.

PSC 134.14(5) (5) 

PSC 134.14(5)(a) (a) Whenever a meter with a rated capacity of 400 cubic feet per hour (CFH) or more is found to have a weighted average error of more than 2% slow, the utility shall bill the customer for the amount the test indicates has been undercharged for the period of inaccuracy, which period shall not exceed the last 2 years the meter was in service unless otherwise ordered by the commission after investigation. No back billing for an inaccurate meter will be sanctioned for the following:

PSC 134.14(5)(a)1. 1. The customer has called to the company’s attention his or her doubts as to the meter’s accuracy and the company has failed within a reasonable time to check it.

PSC 134.14(5)(a)2. 2. The rated capacity of the meter is 399 cubic feet per hour (CFH) or less.

PSC 134.14(5)(a)3. 3. The amount of the backbill is less than $50.

PSC 134.14(5)(b) (b) Backbilling shall be required for any size meter for any of the following circumstances.

PSC 134.14(5)(b)1. 1. The meter did not register.

PSC 134.14(5)(b)2. 2. An incorrect correction factor or meter constant was applied.

PSC 134.14(5)(b)3. 3. The meter or service were tampered with.

PSC 134.21 PSC 134.21 Heating values and specific gravity.

PSC 134.21(1) (1) Each utility which is furnishing gas service shall have on file with this commission for each municipality served the heating value, specific gravity, and composition of each type of gas regularly supplied and also for the gas which may be used for standby purposes and the range of values for peak shaving. The heating value filed shall be the total heating value with the indication whether it is on a wet or dry basis. (See definitions in s. PSC 134.02.)

PSC 134.21(2) (2) All gases whether the regular gas supply, a mixture of gases or a substitute gas used for peak shaving purposes shall operate properly in normal gas utilization equipment. Where used for emergency or standby, the gas shall operate reasonably well in such equipment. (The customer requiring gas of a particular chemical composition shall make such arrangements as may be required to protect against damage by reason of change in composition.)

PSC 134.21(3) (3) The monthly average heating value of the gases as delivered to the customers in any service area shall not be less than the heating value standard on file with this commission and the heating value at any time at constant specific gravity shall not be more than 5% above or 4% below this standard. At constant heating value, the specific gravity of the gas shall not vary more than 10% from the standards filed with the commission. If the heating value is varied by a greater amount than specified, the specific gravity shall be varied in such a way that the gas will operate satisfactorily in the customer’s utilization equipment. Customers using processes that may be affected by a change in the chemical composition of the gas shall be notified of changes. Agreements with such customers shall specify the allowable variation in composition.

PSC 134.21(4) (4) For required periodic heating value tests see s. PSC 134.25. The specific gravity of the gas shall be determined at least once each month when there is no change in the type or sources of gas and when there is a change in the type of gas. Whenever emergency or peak shaving plants are ran or when mixed gases are used, daily determinations of specific gravity shall be made.
